SqlBulkCopy - Cannot access destination table '[TheInvalidTableName]'.

Problem

You execute the method WriteToServer, and the following error is thrown:

Cannot access destination table '[TheInvalidTableName]'.

using(var connection = new SqlConnection(FiddleHelper.GetConnectionStringSqlServer()))
{
    connection.Open();
    using (var sqlBulk = new SqlBulkCopy(connection))
    {
        // Oops! The destination name is Customer instead of Customers 		
        sqlBulk.DestinationTableName = "Customer";
        sqlBulk.WriteToServer(dt);
    }
}

Try it

Solution

Cause

• You provided an invalid schema name.
• You provided an invalid table name.
• The user doesn't have the right to the schema name.
• The user doesn't have the right to the table name.

Fix

• ENSURE the schema name is valid.
• ENSURE the table name is valid.

using(var connection = new SqlConnection(FiddleHelper.GetConnectionStringSqlServer()))
{
    connection.Open();
    using (var sqlBulk = new SqlBulkCopy(connection))
    {		
        sqlBulk.DestinationTableName = "Customers";
        sqlBulk.WriteToServer(dt);
    }
}

Try it

If the schema and table name was already valid:

• LOG into SSMS with the user/password used by the application and perform a SELECT statement to ensure he has access to it.
